But still,

If I sync immediately after rebuilding the freelist, the
kfs works fine. If I let syncproc do that, wrenwrite is passed
offsets not present in the file system eventually.

After a lot of investigation, I can only image a possible
cause in insufficient interlocking, but fail to understand
how this happens. 

This is not a hardware problem, I am able to reproduce it
with a different fast enough computer.
